| When I use the command "if (ImageEnMView.MIO.Acquire) then" if an error occurs during scanning, is to retrieve the scanned pages? Why did he "ImageEnMView.ImageCount = 1"? |

Hello xequte, only to complement the occurrence above, this only occurs in the "TWAIN". In the WIA interface, even if error, it keeps the pages scanned so far. I would like to work the same way! |

| Even with Twain you should have all pages actually acquired, excluded, of course, what caused the error. Anyway let me do some tests. |

| Fabrizio In my tests, I'm using the latest version 4.1.0 with the Kodak i1220 scanner, delphi 7, Win7 64B, 4GB Memory and Core i5. When I'm scanning the hopper, secure the sheet so that the error occurs, simulating what happens in a client company. In WIA works, returning the pages scanned so far, but the TWAIN does not work. |

I just sent to your private email an ImageEn testing version, that should enhance this behavior.
Anyway I experienced this (I don't if this is i1220 specific): failure page is always sent. Not always previous pages are sent. Of course ImageEn gets what the twain driver sends. |

Fabrizio, I auditioned at the Kodak i1320 and the same error occurs. Get the latest scanner error, it returns me the following: "General failure. Unload Source immediately."
And as I said, it returns me a scanned page in black and white, and the remaining pages never comes. Only I have the Kodak i1220 and i1320 models, I would like if possible, you apply some tests in the same way you did before, only this time with a manufacturer other than Kodak. |

I have the same device and I can replicate this behavior. As already told this device stops sending data of already acquired pages when an error occurs. |

So this is a kodak scanner device problem?
What about the question of the topic "http://www.imageen.com/ieforum/topic.asp?TOPIC_ID=498" for Duplex scanning in "TWAIN" I only returns a page with the verse and the other scanned the totally black?
It is also a problem of kodak scanner device? |
